Abstract
A method for physical separation and purification of bioactive phenolics from fruits, berries and vegetables by subjecting a fruit, berry or vegetable extract solution having a Brix of from about 1 to about 4 to ultrafiltration using an about 2,000-6,000 Dalton cutoff ultrafiltration membrane under a pressure of about 30-120 psi, and a temperature of about 80-110° F. This is followed by subjecting the resulting retentate to diafiltration-ultrafiltration with the addition of water, using an about 2,000-6,000 Dalton cutoff ultrafiltration membrane under a pressure of about 30-120 psi, and a temperature of about 80-110° F., and recovering the diafiltered retentate or the bioactive phenolic containing solids thereof.
